Back in the last millenium there were a bunch of companies that made
clones of IBM mainframes. They all failed.

They didn’t “fail” as such. Companies like Amdahl and Wang were able to
maintain profitable businesses for quite a few years, decades even. And
then there were other entirely separate companies, like CDC where Seymour
Cray invented the concept of the “supercomputer”, much to the surprise of
his upper management who just wanted to sell “business” machines.

All the mainframe companies apart from IBM eventually went out of business
because the whole mainframe concept is obsolete. The only reason IBM is
still going is because it was able to muster more marketing clout than all
its competitors put together. But even that part of its business is in
decline. The only part of the company currently making money would be its
Red Hat acquisition. The rest will eventually wither away.
